The
procedure
in
the table
below
shows
all
that
is
necessary
to completely
'AUTOCAL'
the
DC
Current
function.
lf
just
the
DC
Current
or
just
one
range
of
DC
Current is
to be
calibrated,
then
step
11
lo
14
of the
DC
Voltage
Calibration
table
should
be
carried
out
first'
Then on
each
DC
Current
range
iust
a
'Zero'
and
'Gain'
calibration
is
required.
lf the 'DVM
Reading After
Calibration'
is
not
in
accordance
with
the table then
repeat
operation
of
the
same
'CALIBRATE'
key is
permissible
to
improve
the
reading.
Where
no
tolerance
is shown
in
this
column,
only
the exact reading
quoted
with an
occasional
least
signif
icant
digit
showing
is to
be expected.

Checking
Accuracy after'AUTOCAL'
To
check
the accuracy
after
'AUTOCAL'the
'Speci-
fícation
Verification'
section
of
the
Operating
Handbook
will
be useful.
lt
provides
tables
for
quick
reference
of
